工序

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.

序 = 予 + 广 : Due to an emergency Xu Xian (xu) and Zai Yu (予) both have to leave the space station from the bathroom (Ø4) and parachute (广) back to earth. They just cannot decide on the sequence (序) of who's going first.
